Gyrolite, Quartz, Calcite from Jalgaon, Maharashtra, India [db_pics/pics/indi-34c.jpg]

This is a nifty Indian combo specimen. On a matrix of basalt, drusy, white, quartz formed first followed by gray spheres of calcite, to 1.75 cm across, then glassy, colorless, quartz, to 2.5 cm in length, and lastly, balls of white gyrolite, to 3.25 cm across. The gyrolite has a matte luster with superb translucence. Rarely do you see such large aggregates of this species, and so it is significant as well as nice for the display qualities.

Sharp crystals with the utterly brilliant lustre and internal sparkle that seem to characterise this find. The largest crystal is 1.7 cm. One doubly-terminated crystal is just over 1 cm.

Particularly intense purple crystals with the utterly brilliant lustre and internal sparkle that seem to characterise this find.

A dramatic, complete all-around, tower of crenellated smoky quartz perched centrally on and impaling a matrix of albite and smaller quartz! The quartz is actually doubly-terminated, though you'd want to stand it on the bottom termination in a base (provided inclusive). The brilliance and lustre of the specimen are superb, and top quality. It is complete all around and, if you have a showcase deep enough, makes a very visual impact between teh combintaion of gemminess and form.

Rose Quartz on Quartz from Lavra da Ilha pegmatite, Jequitinhonha River, Taquaral, Itinga, Minas Gerais, Southeast Region, Brazil [db_pics/pics/j08-10d.jpg]

Rose quartz is the rarest and most prized quartz varietal, and good specimens are always sought-after by collectors – particularly when they show a unique aesthetic quality as this one does. This is an exquisite "fan" of translucent, tightly-intergrown crystals that has grown on a crystal of colorless quartz. The rose quartz rises about 3 cm to its ridge of terminations. The crystals have a wonderful sparkly luster, better in person. Old specimen from the famous 1960s finds at this island in the middle of a river, noticeably classic for the find due to the matrix arrangement and overall "look". Ex. Kirby Siber collection (Switzerland)

A MAJOR ferberite for this important locale....and, No, this is NOT a super ferberite specimen from the plentiful finds in China, but a much more uncommon KOREAN specimen that came out of the Rolf Wein Collection in Germany, which was dispersed around 2004-2005. What makes it extraordinary is not just its excellence for this locality, and in fact its overall quality by any standard, but also its amazing aesthetics: the large, 7.5-cm ferberite crystal is locked inside gemmy, translucent quartz crystals! Its termination, in fact, extends right up into the crystal on the left side. Ferberite is not typically a remarkably pretty mineral, so the fact that this specimen is so attractive and dramatic overall adds a lot to its existing desirability as a fine locality specimen from one of the most classic localities for tungsten minerals. Ferberite also , I can say, does not seem to occur often as inclusions. I cannot think of another piece I know with similar aeshtetics.

Fluorite Fried Egg on Amethyst from Mahodari, Nasik, Maharashtra, India [db_pics/pics/j08-20b.jpg]

Botryoidal fluorites are rare. They are best known from this Indian locality, and from a recent find in China (purple ones). These Nasik ones have always been popular, not only due to their relative uncommoness, but also the fact that they are just plain "cool." This one, however, stands above many of the rest, in my opinion. First, it is UNUSUALLY translucent for one of these – in fact, you can faintly see all the way through it! Second, it is complete all around, with no contacts, and perfectly round. And finally, it is nestled in a perfect "nest" of light purple amethyst crystals as opposed to the normal white quartz. What in incredibly eye-catching and unusual mineral specimen, in every respect!

Quartz and Prehnite from Brandberg, Namibia [db_pics/pics/j08-25c.jpg]

The vast majority of Brandberg quartz specimens are single crystals. Of those that are matrix specimens, a very small number are associated with prehnite, as this one is – and it adds so much to the beauty of this specimen. I also like the attractive isolation of the lone, gemmy quartz crystal with its elegant blush of smoky color at the termination. Note the small bloom of some kind of pseudomorph (we think) crystals on the side of the quartz crystal.
